The two figures are similar. The height of the bigger figure is [[$ h $]] and the width of the smaller figure is [[$ u $]]. The area of the larger pattern is denoted by [[$ A $]]. The letters [[$ a $]] and [[$ b $]] are some numeric values. Which of the following equations can be true and which of them are absolutely false?



a) [[$ u = ah $]]

can be true is true is false

b) [[$ u = abh $]]

can be true is true is false

c) [[$ u = bh + a $]]

can be true is true is false

d) [[$ A = bh $]]

can be true is true is false

e) [[$ A = bh^2 $]]

can be true is true is false

f) [[$ A = ah^3 $]]

can be true is true is false
